What is the long term vision here? Is the idea that consumers will have little apps here and there that will procedurally interact with the owner's data on Dropbox? Or, is Dropbox making a product along the lines of S3 so that backends can consider using it too? I guess given how expensive space is at this point, that's not really an option.
